Using the ethnographic record, this study develops and tests the idea that community permeability may be used as an archaeological predictor of warfare. With the exception of pastoral societies, community permeability predicts warfare.

This article uses pre-defined criteria to sample 22 archaeological climate-related disasters from 9 distinct regions from eHRAF Archaeology. It quantitatively tests four hypotheses regarding change in conflict following climate-related disasters using multiple regression analyses and backwards stepwise regression. Findings demonstrate association between political strategy/authority decision making and degree of post climate disaster conflict.

This article discusses the use of analogy to interpret the archaeological record. The author argues that Murdock's method of cross-cultural research is especially valuable for archaeological analogy. Some of the author's previous studies are presented in support of this argument.

In the present study, Peregrine tests two perspectives regarding social resilience to climate-related disasters: 1) that societies with more inclusive and participatory political structures (corporate political strategies) are more resilient to climate-related disasters, and 2) that societies with tighter adherence to social norms are more resilient to climate-related disasters. Results support the notion that societies with greater political participation are more socially resilient to catastrophic climate-related disasters. Because these results are justifiably generalizable across multiple historical and cultural contexts, Peregrine's findings are a useful contribution to aid in disaster response policy decision making.

This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

The author analyzes conditions that might favor social resilience during the Late Antique Little Ice Age (ca. 536-556 CE). The assumption is made that climatic conditions in the Northern Hemisphere during this period of time are very similar to those that would occur during a nuclear winter. These conditions include a drop in temperature and decreased solar radiation from volcanic eruptions. Measures for social resilience come from multiple variables for social change, which are tested against measures for type of political engagement. It is argued that broad political participation is correlated with resilience.

This article discusses the reasons behind advances in craft specialization particularly why there is a relationship between advances in craft specialization and the emergence of powerful elites. Hypothesis tests focused on political centralization.

This article examines cultural forms of population control. Results suggest that female infanticide and warfare are interrelated and effective forms of population control.

This study examines several correlates of the shape of floor plans of dwellings. Authors find that "whether a culture is settled or nomadic, the form of its family and the presence or absence of status distinctions are related to its house type, and the house types can in turn be inferred from the floor plan." Curvilinear houses are associated with polygyny and nomadism and rectilinear houses are associated with sedentarism, extended families, and status distinctions.

This article draws from previous research by Ember and Ember (1992) that suggests a relationship between socialization for mistrust in others, unpredictable natural disasters, and warfare frequency. Authors hypothesize that the inclusion of a corporate-network strategy variable will improve the predictive power of the Embers' model for warfare. Results support this hypothesis.
